Thread subject: Diptera.info :: Melanostoma

I don't want to flood the forum with too many contributions a day, so only this last one today...
I still have difficulties to distinguish the two main Melanostoma
species here in Ostwestfalen/Germany, M. mellinum
and M. scalare
, which are both numerously on the wing currently. The keys only give attributes which can't be seen on a lower res photograph, but is it generally correct that the yellow markings on the male abdomen of M. scalare
are broader than on M. mellinum
So, is this a male M. mellinum
And this a male M. scalare
And what about this female?
Last not but least another syrphid. I think this is Dasysyrphus albostriatus
